Frequently asked questions
Does this give me an official UPC number?
No. It draws a barcode for a number you already have. Official UPC numbers for selling in stores come from GS1, the standards organization that licenses company prefixes.
What is the check digit?
The 12th digit is calculated from the first 11 so scanners can detect typos. Enter 11 digits and the tool adds it; enter 12 and it checks yours.
PNG or SVG?
SVG stays sharp at any size and is best for print labels. PNG works everywhere for quick use.
Can I make EAN-13 barcodes too?
Yes. The same barcode generator supports EAN-13 and other formats; change the symbology on the page.
Is anything uploaded?
No. The barcode is drawn in your browser.
